A convincing demo is not a slide deck. For a WordPress MCP product, the demo has to prove the full loop: inspect the site, perform the action, and verify the result. If any of those steps are missing, the user is forced to guess.
What to show
The current page or site state before the change.
The actual tool or workflow being used.
The rendered result after the write completes.
What not to show
Do not show only prompt text and call it proof.
Do not hide the WordPress response if the product claims real operational control.
Why this matters
The buyer needs to see a closed loop, not a promise.
That loop is what turns curiosity into confidence.
Takeaway
A good demo proves the product can operate a real site safely.
That is more persuasive than any amount of abstract product language.
